    Question Arduino IDE Serial Monitor output on Linux

    Hello all!

    I've begun coding for the ArbotiX and the Dynamixel AX-12 servos using the Arduino IDE on Ubuntu Linux (with the BioloidController library). I've installed and configured everything according to the online instructions for the Arduino and the ArbotiX, and I'm able to load programs and control my servos no problem.

    My problem lies with the Serial Monitor in the Arduino IDE. I'm trying to display servo data like position, load etc., and program debug output, but nothing will output to the Serial Monitor. Even a simple "Hello World!" produces no output.


    #include <ax12.h>

    void setup() {

    void loop() {
    Serial.println("Hello World!");

    I read somewhere that the Serial Monitor on Linux will not work correctly with certain versions of GCC (edit: programs compiled with certain versions of GCC). I'm hoping someone here can help!

    My setup is as follows (some of which I realise is redundant given my problem, but just in case... ):

    Ubuntu 10.04 LTS (32-bit version)
    ArbotiX Robocontroller and the Pololu ISP
    AX-12 servos (from the Bioloid Comprehensive Kit)
    Arduino 0018 (with the BioloidController library)

    From a terminal my versions of gcc (gcc --version) and avr-gcc (avr-gcc -version) are as follows:

    gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3
    avr-gcc (GCC) 4.3.4

    Does anyone else have a similar setup to mine and experience or knowledge of this issue?
